Where did this key come from? It feels a little unsafe to include a plaintext API key like this.

[ylemkimon]

@kevinbarabash It is provided by Algolia. It is Search-only API Key, which is safe to use in front-end code and in production. Also, Docusaurus documentation suggests entering the API key to its configuration: https://docusaurus.io/docs/en/search.

The configuration for our DocSearch is available at: https://github.com/algolia/docsearch-configs/blob/master/configs/katex.json.

One question is should we include supported functions in tables, i.e., tds?

Not sue. It looks things are set up to use td so let's give that a try. I assume we can change it later if need be.

[kevinbarabash]

Thanks for setting this up. I'm curious to see how well it works with our current docs.

I should've given it a try on the netlify test site before accepting the review. I did just now, and it seems to be working. I think a lot of people will find this really handy. Thanks for adding it.
